Frequently asked questions
Which free astrology calculator should I use first?
Start with a birth chart or zodiac sign calculator if you are new. Use the Big Three calculator when you know your exact birth time and want a more complete first view.
What are my Sun, Moon and rising signs?
Together they are often called the Big Three: core direction, emotional habit and the way you meet the world. Birth time matters for the rising sign.
Can astrology calculators check relationship compatibility?
Yes. Start with a broad zodiac comparison, then use Moon, Venus, Mars or synastry tools to explore a more specific relationship question.
How can I find all twelve houses in my chart?
Enter your rising sign in the astrology houses calculator to map all twelve Whole Sign houses and their life areas.
What should I ask during an astrology or spiritual reading?
Use one open question about love, career, timing or personal growth. A question generator can turn a vague concern into a focused prompt.
